Audio system stops working after some resume from sleep while connected to usb-c dock

English Multimedia
1

After some time, usually after several resumes from sleep the audio system seems to be broken. The symptoms are:

  • no sound output
  • cannot change sound output from dock to laptop’s own speaker, but there is no sound to the dock audio.
  • videos in firefox do not start, probably it is waiting to the audio system

It started a few weeks ago when I have updated tumbleweed after several months. Before it was running without problems, my install is 4 years old. I almost always have my laptop connected to a usb-c dock and I use hybrid-sleep. I run Tumbleweed.

The only solution is to do a systemctl --user restart pipewire.service switch devices back and forth and it works again. What can be the problem?

It might be interesting to query the journal for events following the resume perhaps. If you know the time of the resume, you could use something like
journalctl --user -u pipewire -u wireplumber --since "2025-09-20 20:42:00"

Also it might be useful to compare the output before and after the hybrid sleep / resume cycle…
wpctl status

Does plain suspend / resume behave the same with respect to the audio services?

I have the same problem and I think it started a week ago, from time to time after resuming from sleep audio do not work ( some applications like web browsers do lag because of that ) trying to put the computer to sleep again and resuming again while in this state do not solve the issue, restarting the user session or restarting the pipewire service ( plus all applications using audio running ) do solve the issue.

In my end the relevant logs when running journalctl --user -u pipewire -u wireplumber

Here the computer was put to sleep arround 12:46 and resumed from sleep at 16:19, also I’ve check the status of the pipewire service before and after restarting it

Will do next time I face the issue, all the tests mentioned above were made before finding this thread, I’ve just tried again to go to sleep then wake up but everything went fine except that it did take longer than usual for the computer to go to sleep but it could be normal since I’ve manually restarted the pipewire service and did not restarted the session since …

So the issue happen again, when looking at the journal journalctl --user -u pipewire -u wireplumber the same error as before with wireplumber that occur when putting the computer to sleep happen.

This time I’ve looked the status of the wireplumber service while in the broken state

And I’ve tried to restart only the wireplumber service and it did fix the problem, I didn’t even had to restart any running application to have the audio working again.

As for the wpctl status before and after restarting wireplumber openSUSE Paste

So far I could not catch the moment when it goes wrong since I do not use the audio system constantly. When I resumed today it was wrong, however there was nothing in journalctl.

I have realized now, that the problem appears when I connect and disconnect a bluetooth device, journal says:

The stack traceback seems to be the same as for Aboutduck

Have the same problem.
When I disconnect my bluetooth headphone, or when my system comes out of sleep.
When I try to play a song (strawberry) nothing happens and after a few seconds this appears:
